Uyivikela kanjani i-aluminium ku-oxidation?

Akekho umkhiqizi ofuna ukubona i-aluminium ene-oxidized—kuyishwa ukuguquguquka kombala okubonisa ukugqwala okuzayo. Isibonelo, uma umkhiqizi wensimbi ye-aluminium enemikhiqizo evezwe endaweni enomswakama, i-oxidation noma ukugqwala kungaba yinkinga ebizayo. Umoya-mpilo osemoyeni uhlangana ne-aluminium, wenze ungqimba oluncane lwe-aluminium oxide ezindaweni eziveziwe. Lolu ngqimba lwe-oxide alubonakali ngeso lenyama kodwa lungenza buthaka indawo engaphezulu futhi lufake engozini ikhwalithi yamashidi e-aluminium.

Iyini i-Aluminium?

I-Aluminium iyinsimbi evame kakhulu emhlabeni wethu futhi inikeza ukusebenza okuningi. Kuyinsimbi ethambile ethandeka kalula, ekwazi ukumelana nokushisa, futhi imelana nokugqwala. I-aluminium ehlanzekile ayenzeki ngokwemvelo futhi ayizange ikhiqizwe kwaze kwaba ngu-1824, kodwa ama-aluminium sulfate nama-compound atholakala ezinsimbi eziningi ezenzeka ngokwemvelo.

Ngenxa yokuhlanganiswa kwayo nezinsimbi, i-aluminium itholakala ezintweni ezihlukahlukene: izitsha zasekhishini, izingxenye zezimoto, amatshe ayigugu, amafreyimu amafasitela, ama-air conditioners, njalonjalo. Uma kucatshangelwa ukuguquguquka, kungenzeka ukuthi uphambi kwento ye-aluminium khona manje. Ivamise ukuthandwa ngaphezu kwezinye izinsimbi ngenxa yenhlanganisela yamandla, ukumelana nokugqwala, isisindo esiphansi, kanye ne-ductility. Kodwa uma uzotshala imali emkhiqizweni we-aluminium, kufanele uthathe izinyathelo zokuwuvikela ekugqwaleni.

Iyini i-Aluminium Oxidation?

I-aluminium oxidation iyisiqalo senqubo yokugqwala kwe-aluminium ngemva kokuhlangana nomoya-mpilo. I-oxidation yenzeka ukuze kuvikelwe i-aluminum ukuthi ingagqwali ngokuqhubekayo. Ingase ibonakale njengokushintsha kombala noma njengombala ongekho mhlophe.

I-Aluminium ayizwani nokugqwala, okusho ukuthi ayoni ngenxa ye-oxidation ebangelwa insimbi nomoya-mpilo. Ukugqwala kwenzeka kuphela ensimbini nakwezinye izinsimbi eziqukethe insimbi. Ngokwesibonelo, insimbi ingagqwala kalula ngoba iqukethe insimbi. Ngaphandle kwalapho kuwuhlobo olukhethekile lwensimbi ekwazi ukumelana nokugqwala, njengensimbi engagqwali, izothuthukisa ama-flakes anombala wethusi aziwa ngokuthi ukugqwala. I-Aluminium ayinayo insimbi, noma kunjalo, ngakho-ke ivikelekile ngokwemvelo ekugqwaleni.

Noma ingagqwali, i-aluminiyamu isengaphathwa ukugqwala. Abanye abantu bacabanga ukuthi ukugqwala nokugqwala kuyafana, kodwa lokhu akulona iqiniso ngempela. Ukugqwala kubhekisela ekuwohlokeni kwensimbi okubangelwa ngamakhemikhali okubangelwa izakhi zemvelo. Uma kuqhathaniswa, ukugqwala kubhekisela ohlotsheni oluthile lokugqwala lapho insimbi i-oxidize kusukela ekuchayekeni komoyampilo. Futhi, i-aluminium ingakwazi ukugqwala, kodwa ayikwazi ukugqwala. Ngaphandle kwensimbi, i-aluminium ivikeleke ngokugcwele ekugqwaleni.

Kungani Ususa I-Aluminium Oxidation?

Izizathu ezimbili eziyinhloko zokukhipha i-aluminium oxidation ubuhle kanye nokuvimbela ukugqwala okuqhubekayo.

Njengoba kushiwo ngenhla, i-aluminium oxidation idala ukushintsha kombala noma umbala omhlophe. Lo mbala ungase ungakhangi ukuwubuka ngoba ubonakala ungcolile.

Lapho i-aluminium iqala ukugqwala, izoba buthaka. Njengokugqwala, ukugqwala kudla insimbi efanele. Lena akuyona inqubo esheshayo. Kunalokho, kungathatha amasonto, izinyanga, noma ngisho neminyaka ukuze umkhiqizo we-aluminium ugle. Nokho, uma kunikezwe isikhathi esanele, imikhiqizo ye-aluminium ingakha izimbobo ezinkulu ezibangelwa ukugqwala. Yingakho kubalulekile ukuvimbela i-aluminiyamu ekugqwaleni.Ohlangothini olungokoqobo lokususa i-aluminium oxidation, ukuhlanzwa njalo kuvimbela i-aluminium yakho ekubeni i-oxidizing noma ukugqwala ngokuqhubekayo. Uma isikhathi eside i-aluminium i-oxidize, kuzoba nzima kakhulu ukuyisusa. I-aluminium oxidation ekugcineni izokwenza umkhiqizo we-aluminium usebenze kabi.

Uyihlanza kanjani i-aluminium ene-oxidized?

Yiba nesimiso sokuhlanza esivamile

Isinyathelo sokuqala sokususa i-oxidation ku-aluminium ukungena kumkhuba wokuhlanza okuvamile. Lokhu kubaluleke kakhulu uma uqala ukubona izimpawu ze-oxidation. Qaphela ukushintsha kombala, amachashaza amhlophe, nenhlaka. Uma ungazinaki lezi, zizokwakha futhi zibe nzima ukuzikhipha ngemva kwesikhashana.

Ukuze uqale ukuhlanza okuvamile, udinga amanzi athile noma indwangu emanzi, kanye nensipho ethile. Qala ngokuwasha into yakho ye-aluminium ukuze ususe ukungcola nothuli. Lokhu kungenziwa kusinki, ngepayipi, noma ngendwangu emanzi. Uma uhlanza amasondo e-aluminium noma i-side, qiniseka ukuthi uyayihlanza kahle njengoba ukungcola kubambeka kalula emifantwini yawo.

Ngemuva kwalokho, yigeze kahle ngensipho - gwema ukusebenzisa ibhulashi nanoma yini efanayo ngalesi sikhathi. Uma i-aluminium ibonakala ihlanzekile, yisule kahle bese uyigcina endaweni eyomile. Uma isabukeka i-oxidized, noma ukungcola kufakwe amakhekhe ensimbi, sebenzisa izindlela zokuhlanza ezilandelayo.

Sebenzisa isixazululo sikaviniga omhlophe

Ukuze uqale ngale ndlela yokuhlanza, qala uthole ibhodwe lamanzi. Faka izipuni ezimbili zikaviniga kuzo zonke izinkomishi ezine zamanzi. Xuba lesi sixazululo kahle bese usilethela ngamathumba imizuzu engu-15. Ungasebenzisa le ngxube ngezindlela eziningi. Ungathela usinki wakho we-aluminium ngawo bese uwuthululela phansi emseleni ukuze ususe ungqimba olune-oxidized. Ungakwazi futhi ukushiya izinto ezincane ze-aluminium ebhodweni imizuzu embalwa ukuze ukhumule ungqimba. Ungathola i-rag namagilavu ​​athile futhi usebenzise lesi sixazululo kumafreyimu amafasitela kanye nefenisha yangaphandle. Uma ungqimba lwe-oxidized luphikelela, sebenzisa ibhulashi elithambile le-bristle bese ukhuhla ngobumnene isixazululo sikaviniga ku-aluminium. Lokhu kungaphakamisa amamaki e-oxidation asele ebusweni.

Sebenzisa ingxube yejusi kalamula

Uma ungenawo uviniga omhlophe, ungazama ukusebenzisa ulamula. Okokuqala, usike ulamula phakathi, bese ucwilisa uhlangothi oluvulekile kusawoti othile. Sebenzisa ulamula onosawoti njengebhulashi lokukhuhla bese uqala ukusebenza emkhiqizweni we-aluminium. Faka futhi usawoti uma kudingeka. Lokhu kufanele kususe amamaki amaningi - uma kungewona wonke - ebusweni bomkhiqizo. Ukuze uthole amamaki aphikelelayo, zama ukubilisa enye ingxenye kalamula emanzini imizuzu engu-15. Sebenzisa la manzi kalamula ukuze ugeze i-aluminium yakho, bese uqala ukukhuhla ngesigamu sikalamula kasawoti futhi kuze kunyamalale izimpawu. Le ndlela isebenza kahle ngefenisha ye-aluminium, amabhodwe, namapani.

Sebenzisa imikhiqizo yokuhlanza ezohwebo

Izihlanzi eziningana zezentengiselwano zingasusa i-oxidation. Uma unquma ukuzisebenzisa, qiniseka ukuthi izinto zokuhlanza ozithengayo zenzelwe i-aluminium ngokuqondile. Uma kungenjalo, ingakwazi ukugoba futhi idle insimbi.

Ngemva kokukhipha i-oxidation eningi ngangokunokwenzeka ngokusebenzisa ezinye izindlela zokuhlanza, gqoka amagilavu ​​futhi usebenzise isicoci sokuthengisa ngokuvumelana neziqondiso ezinikezwe emaphaketheni aso. Ungasebenzisa futhi i-metal polishing paste noma i-wax efanele i-aluminium. Ukusebenzisa le mikhiqizo kuzonikeza isiphetho esicwebezelayo, futhi kungasiza ukuvikela insimbi ekufakweni kwe-oxidation ngokuzayo. Ukusebenzisa i-wax kunconywa kuphela kumasondo e-aluminium, amafasitela namafreyimu eminyango, kanye nefenisha yangaphandle.

Hlanza ngokujulile imikhiqizo yakho ye-aluminium

Uma - ngemva kwazo zonke lezi zindlela - kusekhona amamaki anenkani ambalwa emikhiqizweni yakho ye-aluminium, sekuyisikhathi sokuhlanza okujulile. Sebenzisa amanzi ashisayo, ithuluzi elinomphetho oyisicaba (kungaba i-spatula), bese uqala ukuhlanza. Geza noma umboze into emanzini ashisayo imizuzu embalwa, bese usula i-buildup ebusweni. Uma ugeza izinto ezinkulu njengefenisha noma i-aluminium siding, bese cwilisa indwangu emanzini ashisayo bese uyibamba ngokumelene nongqimba lwe-oxidation ukuze uyixegise, bese usebenzisa ithuluzi lakho ukuze uyisule.

I-Key Takeaway

Nakuba i-aluminium ivikelekile ngokwemvelo ekugqwaleni, ngenxa yezakhi zemvelo ukugqwala kusengenzeka ngenxa yokuwohloka kwensimbi okubangelwa ngamakhemikhali. Kungase kuthathe isikhashana ukuthi i-aluminium igle kodwa kusafanele ivikelwe. Ukuvimbela ukugqwala ku-aluminium kudinga ukuba endaweni elawulwa yisimo sezulu noma iphathwe nge-coating ecacile.
